Yes, bunnys in ArmA 3 wearing body armors (by default of course).
Animals wearing body armor? Sounds stupid? Welcome to ArmA 3 bug report :-)
In ArmA 3 you cannot shoot 2 bunnys in row with 6,5mm rifle. Rifles with smaller caliber (in real life) can sometimes penetrate human body so why in ArmA 3 6,5mm rifle cannot shoot 2 (or even more) bunnys in row? Human body is much harder to penetrate than bunny's body and of course 6,5 is even more than 5,56.
